My invention relates to a wrapping ma chine for safety razor blades.

It is well known that the blades of safety razor apparatus are packed upby wrapping 6 each individual blade into a cover (wrapper or envelope)provided with suitable print which in its shape corresponds with theshape or configuration of the blade and which is provided with flapsalong its sides 10 and ends which are ultimately folded down upon theblade. Usually a suitably shaped lining of oilpa-per or the like isemployed besides this outer envelope.

The invention consists of a machine or appliance for foldingmechanically paper wrappings about the blades of safety razors. Such amachine attains a high speed, has therefore a large capacity and effectsa great economy in labor, while the package is neater 2 than canordinarily be done by hand.

An embodiment of m invention is illustrated in the drawings alhxedhereto. In the drawings:

Fig. 1, is the machine in plan.

F i 2, is an elevation of the device for feeding t e wrapping sheets andproviding them with an adhesive,

' Fig. 3, is an elevation of the device for producing and feeding thelining sheet,

Fig. 4, is a sectional elevation of the mechanism for introducing theblade and closing the wrapper,

Fig. 5, is an elevation of the mechanism for lifting the wrapped bladeand conveying the same out of the machine,

Fig. 6, is a front elevation of a detail of this mechanism,

Figs. 7 to 10, are diagrammatic illustrations of the manner of effectingthe preliminary creasing of the sheet of paper and introducing the bladeinto said cover sheet, and

Figs. 11 to 13, are diagrammatic illustrations of one process during theclosing of the wrapper.

Like parts are indicated by like numerals of reference in the variousfigures of the drawings.

Referring to the drawings and more particularly to Figs. 1 and 4, is thedriving shaft operated from a suitable source of power. The shaft 30 isjournaled in bearings 31 and 32 of the machine framework and transmitsits motion by spur wheels 33 and 34 to the shaft 35.

This shaft 35 drives the shaft 38 b means of the bevel wheels 36 sheetsof paper by a gearing 200 operated from the shaft 38. The angles 42, 42extend to the entire height of the pile and are mounted upon rails 44which in their turn are fixed upon the side rails 45, 45 of the labelreceptacle.

The withdrawal of the topmost wrapping sheet for the time being iseffected by the lifter 4 which is adapted to be raised and lowered andto be moved to and fro between the pile and the hereinafter describedfeeding device of the machine. The lifting off of the sheet may in wellknown manner be effected by constructing the picker as a suction head incommunication with an air pump. In the embodiment illustrated. the sheetlifter is in likewise well-kn0wn manner designed as adhesive applyingstamp so that certain parts of the wrapper are simultaneously providedwith an adhesive, for instance in the places indicated in shading at cin Fig. 1. However, in accordance with the special manner of subsequentfolding and closing of the. wrapper, the sheet lifter 4 may also be sodesigned that it provides the wrapper with an adhesive in other places,for instance at the places indicated by the reference letter (J) in Fig.1 of the drawings.

The sheet lifter is for these purposes provided with four members orarms 4' extending downwards upon which exchangeable gum stamps 4" may bemounted according to the places of the wrapper to be provided with theadhesive. The lifter 4 is mounted upon a slide 47 adapted to be movedlongitudinally upon a rail 48 by means of a lever 50 pivoted upon a bolt49 on the machine framing, and which by means of a pin 51 fixed upon itsupper end and journaled in a block 52 engages the sliding track 53 ofthe slide 47 in the manner of a slot and crank. The rocking motionnecessa for the displacement of the slide 47 upon the rail 48 in orderto effect the reciprocating motion of the lifter 4,-is imparted to thelever 50-by means of a guide lever 54 from an eccentric upon the shaft38 against which is drawn in a known manner by means of a suitablespring (not shown) the guide roll 201 of an arm 203 pivoted at 202 andhinged to the guide lever 54.

For the purpose of producing the up and down motion of the lifter 4, anup and down motion is imparted to the rail 48 for which purpose the rail48 is by the connecting head 55 fixed upon a rod 56 which is verticallyguided in the bearing 57. At the lower end of the rod 56 is fixed ablock 58 the mouth 59 of which is engaged by the spherical end 60 of anarm 61 which is mounted upon a bolt 62 rotatably fixed upon the machineframing. Upon this bolt is also mounted an arm 63 which by means of auide roller 64 and a suitable spring (not Shown) is kept in engagementwith a cam upon the shaft 38, in such a manner that by the aid of thedouble-armed lever 63, 61 the rod 56 with the rail 58 is caused toperform an up and down motion at the proper time. To prevent lateraledging of the rail 48, an arm 65 is provided upon-the head piece 58 inthe eye 66 of which a pin 67 is fixed which is guided in the eye 67 ofthe framework of the machine.

The application of the adhesive to the rubber stamps 4" is effected in acustomary manner by a roller 68 the shaft 70 of which is journaled inthe receptacle 69 containing the adhesive and is continuouslyrotated bymeans of the sprocket wheels 71, 72 and the chain 73 from the shaft 38.

During its travel from the position shown in Fig. 2 of the drawingsacross the pile 1, the lifter 4 is raised so far that the rubber stamps4" take up the adhesive from the roller 68. Above the pile, the lifter 4is lowered down upon the uppermost wrapping sheet. This sheet adheres tothe rubber stamps 4" and is then lifted off when the lifter 4 ascends,whereupon the slide 47 with the lifter 4 is moved into the workingposition of the feeding mechanism indicated at I in Fig. 1 of thedrawings.

The feeding device may consist of a conveyor belt, chain or the like. Inthe embodiment illustrated, it consists of an intermittently rotateddisc 5 which is journaled upon the upright shaft 75 by means of a hollowshaft 74. The intermittent rotation of the disc 5 is'efi'ected in awell-known manner by a Maltese cross indicated at 76 the recesses ofwhich are engaged by a roller 77 upon the crank 78 mounted upon a shaft79 which is rotated by bevel wheels 80 and 81, Figs. 1 and 4, from theshaft 35.

After the wrapper a has been placed upon the working position I of thedisc 5 by the lifter 4, a U-shaped holder or arrester 3 descends uponthe wrapper which together with a device hereafter described of theWorking place II is moved up and down so that during the ascent of thelifter 4 the wrapper a is retained upon the disc 5 by said holder 3,whereupon the holder is raised and the disc 5 turned through an an le of60 degrees into the working position I in which, if an inner liningwrapper b is to be employed, this wrapper is placed upon the outerwrapper a.

The lining wrapper b may in a similar manner as described andillustrated for the outer wrapper a be withdrawn from a pile and placedupon the outer wrapper. In the embodiment illustrated, however, thelining is made from a continuous web of aper e pulled off a reel 6,Figs. 1 and 3, w ich by means of the shaft 82 is journaled in arms 83'and 83" of side frames 84 and 84" fixed upon the machine plate F. Theweb of paper e passes from the reel 6 over an ad justable tension rod 85between the feed rollers 86 and 87, of which the roller 87 iscontinuously rotated by a sprocket wheel 88 and chain 89 from a sprocketwheel 90, Fig. 1, upon the shaft 41, while the roller 86 rests looselyupon the paper web. The web proceeds over the table 91 belowa holder 92and between the .feed rollers 93 and 94, the latter of which iscontinuously rotated by sprocket wheel 95 and chain 96 from the sprocketwheel 97, Fig. 1, upon the shaft 41.

The holder 92 is by the arm 98 mounted upon a bolt 100 rotatable injournals 99, 99 upon the end of which is fixed an arm 101 engaged by alever 102. At its lower end, the lever 102 is pivoted upon a doublearmedlever 103, 105 which is fulcrumed at 104 and provided upon its free endwith a guide roller 106 which by means of a suitable spring (not shown)is kept in engagement with a cam upon the shaft 41. By this drivingdevice, the holder or arrester 92 is controlled in such a Way that itpresses the paper web e against the table 91 and thus holds itstationary every time an end corresponding with the given length of thelining wrapper has been passed through underneath said arrester by therollers 93 and 94. The piece of the paper web e held between thearrester 92 and the feed rollers 93 and 94 running idle is now punchedout by the two punches 106' and 106" corresponding with the angles w andw of two successive lining pieces, the punched out pieces droppingthrough the recess 107 of the table 91. Simultaneously the punched outlining piece 5 fed forward by the preceding feed motion by the aid ofthe feed rollers 93, 94 above the outer wrapper located upon the workinglace II is severed by the reciprocating knife 108 which cooperates withthe stationary knife blade 109. The reciprocating motion of the punchingplungers 106, 106 and of the knife 108 as well as of the arrester 3connected therewith by the arm 205 is efiected by a common head piece110 fixed upon two rods 111' and 111" which are vertically guided in theeyes 112 and 112' of the standards 84' and 84" and which are directlyraised and lowered vertically by cams upon the shaft 41.

The blade could now be placed upon the superposed wralppers b, a and bewrapped up. In order, owever, that the extremely sensitive cutting edgesof the blade should not be injured during this process, a special devicemay be provided by means of which the wrapper is prior to the insertionof the blade scored or impressed along the lines on which the folding ofthe wrapper is to take pla e subsequently.

For this purpose, notches or folding ralls 112 respectively are providedat the working places, see in particular Figs. 7 to 10, of the conveyingdevice with which folding notches co-operate corresponding edges 113 ofa vertically reciprocating punch 9 so that on the descent of the punch 9by cooperation of the said edges 113 with the said edges or notches 112the outer and the inner wrapper or, if no lining is provided. only theouter wrapper is scored or creased in the manner illustrated in Fig. 9.In order to hold the wrappers during this scoring operation and toinitiate and assist in the operation 1tself. a movably guided presser115 .is resiliently supported in the punch by means of the spring 116and has a lead in relation to the scoring knives 113 so that during thedescent the wrapper is first pressed against the surface 117 of the die10 by the said yielding presser 115 and that the scoring knives 113become operative thereafter. In the same way, the wrapper 1s retained inits correct position by the presser 115 when the scoring knives 113as'end. The up and down motion of the scoring punch 9 takes placesynchronously with that of the cutting knives 106' and 106" as well asof the knife 108 inasmuch as the punch 9 is mounted upon the head piece110 by the flange 118.

As the scoring knife 113 and the scoring die 10 consist ofsteel, thelatter is made by itself in one piece and inserted into a correspondingrecess 119 of the conveyor disc or table 5.

During the next motion of the conveyor disc 5 by one sixth of a completereyolution, the wrappers reach the working position III where theinsertion of the blades 7 takes place. This insertion may take place 1nany suitable manner. In the embodiment illustrated, it is effected insuch a manner that the blades are conveyed into the working station IIIby a feed disc 12 and are here picked up by a suction head and placedupon the wrapper.

The feed disc 12 is with its hub 12' journaled upon the pillar 120, Fig.4, and is intermittently rotated by the s ur wheels 14, 15 and 16 fromthe hollow s aft 74 of the feed disc 5 in the ratio of 2: 1, so thatthere exist 12 intermediate positions of the disc 12. In each of theseintermediate positions, the disc 12 is provided with two pins 121 each,upon which a blade [is placed by hand with its usual holes.

A suction head 122 serves for lifting the blade off the feed disc 12 andfor placing it upon the wrapper at the working station III. The suctionhead 122 is at 123 in communicationwith an air pump 210, Fig. 3, and isable to move up and down as well as .to perform a swinging reciprocatingmotion.

For this purpose, the suction head 122 is adjustable in an arm 11 whichis mounted upon the shaft 124. The shaft 124 is vertically guided inbearings 125' and 125" by two arms 126' and 126" mounted upon the pillar120. At the'lower end of the rod 124 is attached a head 127, Fig. 3,engaged by a lever 129 by means of a link block 128. The lever 129 ispivoted upon a bolt 130 and is held in engagement with a cam upon theshaft 41 by means of a guide roller 131 of its arm 132 by the aid of a:

spring 133.

For bringing about the oscillating or rocking motion of the arm 11, anarm 134 is fixed upon the rod 124 which is connected by the aid of auniversal joint 135 with a guide lever 136 which is connected by auniversal joint 137 with a lever 138 which is pivoted upon the bolt 130and kept in engagement with a cam upon the shaft 41 by an anti-frictionroller 139 and the spring shown in dotted lines.

\Vhen the wrapper attains the working station III, a blade f has alsoarrived opposite this station, the suction head 122 is lowered down uponthe blade f and picks it up, whereupon the head 122 is raised and thearm 11 swung above the working station III. In this position,illustrated in Fig. 10, the head 122 is lowered into the wrapper,releases the blade 7 and is raised again to return into the startingposition illustrated in Fig. 1.

After the wrapper with the inserted blade has reached the workingstation IV by the next rotation of the disc 5, the folding down of theflaps takes place said flaps upstanding in the manner illustrated inFig. 10 of the drawings. a

This folding down may take place in such lot) . away that first thelining only and subsequently the outer wra per is closed or, as in theembodiment il ustrated, by closing both wrappers simultaneously.

The rocking folders 140' and 140" serve for folding the head flaps a, bof Figure 10 and are mounted upon levers 141 and 141", Figs. 1 and 4.The levers are fixed upon bolts 142' and 142 which are positivelycoupled by toothed segments 143' and 143' and the common drive of bothlevers takes place through the bolt 142 which is journaled at 144 and145 and is controlled by a spring 146 tending to maintain the lever 141,and consequently the lever 141", in the inoperative outer positionillustrated in Fig. 1. Upon the lower end of bolt 142' is mounted alever 147' which under the action of said spring 146 in conjunction withan anti-friction roller is kept in contact with the lateral cam surfaceof a drumlike eccentric mounted upon the shaft 35.

The folders 149 and 149 which serve for folding over the side flaps a, bFigure 11 are mounted ondouble-armed levers 19 and 20 which in theirturn are pivoted upon a bolt 150 of a socket 151, and which at theirother ends are connected with the levers 154 and 155 by links 152 and153. The levers 154 and 155 are fulcrumed upon the pin 156 and are keptin engagement with suitable cams upon the shaft 35 by springs (notshown) and guide rollers, as illustrated in Fig. 4 of the drawings forthe guide roller 157 of the arm 158 of lever 154. If the longitudinaledges of the outer wrapper are provided with adhesive at c, Fig. 1, theclosing of the wrapper is effected in such a manner that first the frontflaps a, b of each side are folded down by means of the folders 140' and140", and then by means of the folders 149 and 149" the side flaps a"and b" at each side are folded down, so that the side flaps located infront in the direction of rotation of the disc 5 are folded last by thefolder 149" of the arm 20.

If, on the other hand, as likewise indicated in Fig. 1, the front flapsare provided with adhesive at (d), the side flaps are first folded downand then the front flaps.

The same folding device may also be employed. if the blade is wrapped upin an outer envelope only and without an inner.

lining sheet. A lateral displacement of blade and wrapper cannot takeplace, because owing to the box-like folding recess of the die 10 inrelation to the other surface of disc 5 a hold is offered in anydirection.

During the next rotation of the disc 5 from stat-ion IV to station V thewrapped blade passes underneath a guide or presser plate 22 whichprevents the folded wrapper from bursting open. If the longitudinalflaps of the lining are folded separately from and'before those of theouter wrapper,

a plunger 250, Fig. 11, first descends between the scored flaps a, b,a", b so that it retains the flaps a, Fig. 12, while the flaps b" arefolded down by the slides 149, 149".

The plunger 250 is mounted u on an arm 251 secured to the upper end 0 arod 252, Fig. 4, which is guided in the sleeve-like bearing 253 and isoperated by the lever 254. The lever 254 is pivoted at 255 and isoperated by a cam upon the shaft 35 which acts upon the roller 256 oflever 254.

To prevent turning of the arm 251 in the horizontal plane itcarries uponits extension 257 a pin 258 which is guided in the eye 259. Upon the arm251 there is furthermore provided above the station V a bolt 260, vertcally slidable, which is locked against turning movement by theflattened collar 261 in the guide 262. At its lower end, the bolt 260carries a plate of the approximate size of the razor blade and servesfor holding down by its weight the flaps folded down at the station IV.'

At the station VI, the wrapped up blade is by means of a lifting device.illustrated in Figs. 1, 5 and 6, raised from the feed ng disc upon thelevel of a gutter 24 which serves for conveying the wrapped up bladesout of the machine. The said lifting device comprises a double armedlever 23 and two blade like plates 271, 271" which are secured to thelower end of said lever 23. The other end of lever 23 is connected bymeans of an universal joint 272, 273 with a link 274 which in its turnis connected by, means of an universal joint 275, 276 with a driving arm27 7. Said arm 277 is pivoted at 278 on asuitable socket of the machineframe and is held by a spring 290 with a guide roll 279 in engagementwith a cam indicated at 280 of the driving shaft 35.

If by the cooperation of sprin 290 and rotating cam 280 the outer end oflever 277 is drawn downwards, the lever 23 is swung by means of theconnecting rod 274 upwards, and the plates 271, 271" will pass throughthe slots 161, 161" and thereby lift the blade so far that it will, inthe uppermost position of plates 271, 271", fall from the preferablyinclined supporting edges of said plates 271, 271" upon the bottom ofgutter 24 and slide on said bottom out of the machine.

It will be understood by those skilled in the art that various chan 'esand modifications may be made in the lnvention without departing fromits spirit or sacrificing any of its advantages.
